Pathnames is free, you can name your program anything your OS allows for
a file. A convention is to name the script ending with .py/.pyw
extension (command-line script/GUI script), although python doesn't
complain if it is not in those extension (in Windows, the extension is
associated with the interpreter). Calling a program from command line is
done like this:
python filename.py

Try renaming the directory c:\python26 to c:\python25 and see if that works. You might also have to modify the PATH and PYTHONPATH environments. If you wish to install python v2.5.2 maybe you need to uninstall v 2.6, just gessing.

[Tutor] Iterating two one dimensional lists to create a multidemsional array
OK I'm still new to the python list / array deal. I'm having problems with
something very simple that I could accomplish in C++ but
for some reason I'm not grasping it python.
Here is my example psuedo code:
I have two lists:
items = ['roses','violets','sugar','so']
and
attributes = ['red','blue','sweet','you']
I have a variable:
action = 'are'
>From the above lists I would like to populate a multi dimensional array that
>would be like this;
poem ={ ['roses','are red'],
['violets','are blue'],
['sugar','are sweet']
['so','are you'] }
I'm assuming I would need two separate loops once through list(items) and then
through list(attributes) and would have to concatenate variable(action) +
str(attributes[0]).
But I'm having a severe brain squeeze right now and cannot get my code to work
as desired.
Could someone please show me what the code should look like?
I know this is very elementary, I also know I can accomplish this in other
languages but the objective is to
get my head around the python version.
Your help would be greatly appreciated.
Thanks

The zip() function is handy for processing multiple lists in parallel.
List comprehensions are handy for processing lists by item. Together
they make short work of this:
In [5]: items = ['roses','violets','sugar','so']
In [6]: attributes = ['red','blue','sweet','you']
In [7]: zip(items, attributes)
Out[7]: [('roses', 'red'), ('violets', 'blue'), ('sugar', 'sweet'),
('so', 'you')]
In [8]: [ [item, 'are '+attribute] for item, attribute in zip(items,
attributes) ]
Out[8]:
[['roses', 'are red'],
['violets', 'are blue'],
['sugar', 'are sweet'],
['so', 'are you']]

Re: [Tutor] Text Scatter Plots?
Title: Signature.html Hi, I'm finally in a position where I might want to use matplotlib. I looked at the site but I'm not sure there's a download for 2.4. There seems to be one ( matplotlib-0.98.1.win32-py2.5.exe)download for Win XP (and other Win OSes). I did see that it requires python 2.3 as a min. Any idea?
